4 Claims.

The invention relates to cosmetic or like holders and more especially to the lipstick elevator cups thereof, the purpose being to produce, at the lowest cost of manufacture, such a holder having 5 a mechanically operated elevator, and consists in the method and article explained below in connection with the drawing which illustrates the method and the preferred form of elevator.

Referring to the drawing, Fig. 1 is an enlarged l central vertical section. of a cosmetic holder of generally known type, the usual cap being omitted and the lipstick elevator being shown in fullyl retracted position.

Figs. 2 and 3 are vertical sections, also enlarged, illustratingthe first step of the method of forming the elevator. Fig 4 is a perspective view of the elevator after the completion of this step. Fig. 5 is a vertical section, and Fig. 6 a side elevation, looking from the right of Fig. 5, illustrating the final step of the method, and Fig. 7

is a perspective view of the finished elevator.

The holder shown in Fig. 1 is of a known type in which an ornamental outer casing l having a liner-sleeve 2 provided with a spiral slot 3, contains a rotatable inner sleeve 4, having an axial slot 5 and an elevator cup 'l which is provided with a stud 6 engaging both slots, whereby it is raised and lowered by relative rotation of the sleeves. Heretofore, this stud or projection 6 has commonly been a separate pin fastened to the elevator by a special operation.

The elevator cup is stamped out of thin sheet metal in an automatic punch press and is formed with a projection 6 produced thereon at one of the stations in the press in which the cup is formed. At such station the cup, inverted, is placed on a suitable die 8, provided with a longitudinal channel 9 along one side and the advancing punch Il which registers with this channel cuts into and through its closed end or bottom end, or the shoulder I0, and shears a short strip out of the `side wall of the cup, beginning at such bottom end, and at the same time curls the strip over on itself for about 360 to the form and position shown in Figs. 3 and 4, wherein it is seen to be a relatively open or hollow external member, which for some lipstick containers may serve as a thumb piece for manual operation but is not adapted for cooperation with slots in lipstick containers such as shown in Fig. 1,

The further `and final step is illustrated in Figs. 5 and 6 and consists in consolidating this curled member 6 into a compact operating lug or pin such as indicated at 6 and which is suited for use in the Fig. 1 holder. This step may be performed at another station in the same press and by any suitable means, that shown being wholly 5 diagrammatic and for the purpose of illustration only. As, shown in Fig. 5 the curled strip 6 is shaped by the cooperation of the two dies l 3--14 which are brought together under appropriate pressure and deform the curl and com- 10 pact its metal into a shape which simulates that of the inserted stud heretofore used on these elevators, that is to say, a stud appropriately rounded to ride easily in the operating slots of the rotary sleeves of the holder.

As the projecting lug can be curled and consolidated in the same automatic press in which the cup itself is formed, its addition to the cup has no eifect in the rate of production and the cup is ready for assembly in the holder without 20 the intermediate stud-alixing operation heretofore generally necessary.

We claim:

1. The method of fabricating an elevator cup for a cosmetic or like holder comprising cutting 25 a longitudinal strip out of the side wall of an elevator cup beginning at its bottom wall and curling the strip into a relatively open external member, and consolidating said member into a compact operating lug or stud. 30

2. The method of fabricating an elevator cup for a cosmetic or like holder comprising shearing a longitudinal strip out of the side wall of a lipstick elevator cup beginning at the exterior of its bottom wall and in the same continuous 35 shearing movement curling the strip on itself into a hollow external member, and consolidating said member into a compact operating lug or stud.

3. The method of fabricating an elevator cup for a cosmetic or like holder comprising cutting' 40 a longitudinal strip out of the side wall of an elevator cup having an annular shoulder between its ends, said strip beginning at said shoulder, and curling the strip into an external member, and consolidating said external member into a 45 compact operating lug or stud.

4. In a device of the kind described, an elevator cup having a laterally projecting external operating stud composed of a consolidated curl rolled up out of the side wall of such cup. 50
